  • Python API for low-level font table access and modification
  • Font subsetter to reduce file size for web deployment
  • Support for UFO (Unified Font Object) format
  • Extensive tools for font analysis and conversion
Use Cases:

  • Converting font formats for cross-platform compatibility
  • Analyzing font tables for debugging and development
  • Building custom font processing pipelines
Alternatives:

  • AFDKO – Adobe's Font Development Kit is focused on font production and validation, often used alongside fonttools.
